Abstract (en)

A computer-implemented method of determining an extent to which an object in a computer-generated scene is visible from a virtual camera, including rendering the computer-generated scene, generating a plurality of points distributed across a surface of the object, determining a depth map value for each point within a field of view of the virtual camera, determining whether each such point is visible from the perspective of the virtual camera based on a comparison between the determined depth map value for the point and a corresponding one or more depth map values stored in a depth buffer populated during the rendering, and determining the extent to which the object is visible in dependence on which of the plurality of points are determined to be visible from the perspective of the virtual camera.
